21 Claims.

This invention relates to certain new and useful improvements in the spinning rings and bar travelers employed in connection with spinning machines.

One of its chief objects is to so design and construct the bar traveler and its spinning 0r bearing ring as to insure a true and uniform action of the traveler and at the same time reduce to a minimum the possibility of the traveler bar being displaced from its operative position.

Another object of the invention is the provision of a bar traveler which is constructed to provide a bearing point at its outer or free ends, thereby bringing its point of wear where breakage of the bar is prevented and insuring its longer life.

A further object is to so construct the spinning ring and bar-traveler that an efficient and effective bearing contact between these parts is provided which affords a more stable and non-whipping action of the traveler, permitting its reliable operation at high speeds, and which affords a material reduction in the tension on the threads and accordingly reducing to a minimum the tendency of the thread to break or be otherwise injured.

A still further object is to provide a device of this character which is simple in construction, efiicient and reliable in operation, and wherein the traveler bar is designed to readily fit different sized spinning rings.

In the accompanying drawing:-

Figure 1 is a top plan view of a spinning ring and bar traveler embodying my invention. Figure 2 is a cross section thereof taken on line 2-2, Figure 1. Figure 3 is an enlarged fragmentary cross section taken on line 3-3, Figure 1. Figure 4 is an enlarged fragmentary sectional plan view showing the manner in which the traveler arms bear against the ring. Figure 5 is a perspective view of the bar traveler. Figure 6 is a perspective view of the slightly modified form of the bar traveler.

Similar characters of reference indicate corresponding parts throughout the several views.

In spinning machines of the character to which my invention is particularly applicable, the threads to be twisted are delivered by feed rolls (not shown) to a take-up spool or bobbin 1O mounted on the same is a vertically reciprocating bar 11, the spool extending through an opening 12 in the bar, as seen by dotted lines in Figure 2.

Mounted on the reciprocating bar 11 and surrounding the take-up spool 10 is the supporting a revolving spindle and traversing base or holder for the spinning or traverse ring upon which the traveler, indicated generally by the numeral 13, is adapted to revolve. During the operation of the spinning machine, the bar traveler assumes a more or less upright or outwardly directed position and revolves with and about the take-up spool, the thread passing under the traveler before being wound upon the spool and the traverse bar being reciprocated so that the threads are uniformly wound in layers upon the spool.

The holder which supports the ring is preferably stamped or formed from sheet metal and consists of an annular attaching base 1 1 having a central opening 15 therein through which the spool 10 extends, and at its outer edge it is provided with a pair of oppositely facing slotted ears 16 for securely fastening the base to the bar. Rising from the outer edge of this base are yieldable clamping posts or brackets 1'? for detachably receiving and holding the spinning ring in place on the holder. The inner edge of the holderbase is provided with an upwardly-facing annular flange or neck 18 which preferably terminates at its upper edge in an outwardly-flaring rim or extension 19.

In its preferred form the spinning ring for guiding the bar traveler about the take-up spool consists of a self-contained track and lubrication unit adapted to be mounted on the holder in frictional engagement with its yielding brackets 17 and is composed of a lower or base-section 20 and an upper or cap-section 21, these sections being fastened as a unit to form a lubricant chamber or reservoir 22. At their outer edges the sections 20 and 21 are provided with depending rims or flanges 23 and 24, respectively, which are nested one within the other and jointed by a pressed fit, the base-section flange 23 preferably extending below the iiange of the companion section and resting edgewise on the top side of the holder-base 14. The outer face of the cap-section flange 24 is adapted to firmly engage the yieldable brackets 1'? to firmly hold the ring in position on the holder. The inner 100 edge of the base-section 20 of the ring is convexly curved, as indicated at 25, to form a supplementary bearing for the traveler, while the inner peripheral face of its flange 23 is preferably arcuate or concave in cross section, as in- 5 dicated at 26, the proper curvature being preferably determined from a radius Whose center is positioned substantially tangentially of the curved bearing edge 25, this concave face constituting the main bearing for the bar traveler. 1

In its top side the cap-section 21 is provided with a filling opening 27 through which the lubricant is introduced into the chamber 22 of the ring.

The bar traveler 18 is constructed of steel wire and preferably shaped in the manner shown clearly in Figures 3, 4 and 5, the same being bent into substantially U -shape to form a thread-engaging or guide bar 28, legs 29 depending from the ends of the bar and arranged to extend freely into the annular space or channel 30 formed between the neck 18 of the holderbase 1d and the inner or supplementary bearing edge 25 of the spinning ring, and extensions or bearing arms 31 projecting outwardly from the lower ends of the legs and adapted to enter the lateral continuation of the channel into more or less hooklike engagement with the ring, in the manner shown in Figures 3 and 4:. These bearing arms are directed outwardly and upwardly at a slight angle to the horizontal and are likewise deflected or bent laterally toward each other at substantially an obtuse angle to the vertical or to a common vertical plane passing through the legs 29 of the bar, as clearly shown in Figures 1 and 4. Short of their free ends, the arms 31 are provided with convex bearing portions 32 which, under certain conditions, are adapted to contact at their upper sides with the underside of the base section 20 of the spinning ring. In the normal operative position of the bar traveler, the free ends of the arms 31 are adapted to abut against the bearing face 26 of the spinning ring, such face being highly finished or polished and the arm-ends riding over this face in a wipinglike manner. During such normal operation, the legs 29 of the traveler run clear of and out of contact with the supplementary bearing face 25 of the ring. Should there be a sudden upward movement of the traveler relatively to the ring, as when the tension of the thread draws up suddenly, then the convex bearing faces 32 of the traveler-arms 31 will contact with the underside of the base-section 20 of the ring. As the end bearing portions of the traveler arms wear, the clearance between the legs 29 and the supplementary bearing face 25 of the ring is gradually lessened and eventually the legs make contact with and bear against such bearing faces 25, at which time the traveler will have a two point bearing with the ring, one at the main bearing face 26 with the ends of the arm, and the other at the supplementary bearing face 25 with the legs of the traveler.

While the cross or guide bar 28 of the traveler may be straight, as shown in Fig. 6, it is preferably shaped in the manner shown in Figures i and 5, the same being bent or deflected inwardly from its opposite ends into substantially the form of a V, which arrangement effectually prevents the thread from working to the corners of the traveler and allows it to traverse the bar between the end thereof and the high point of its bend, thereby preventing the thread traveling over a fixed point and wearing a cut or groove in the cross bar of the traveler, and avoiding the liability of damaging or breaking the thread.

For the purpose of placing the bearing face 26 of the ring in commimication with its lubricant chamber 22, the base-section 20 of the ring is provided in its underside and preferably at the junction or corner between the flange 23 and bottom side of the base-section with an annular groove or channel 33 which is in communication with the lubricant chamber through one or more ports 34. By this construction the lubricant is delivered onto the bearing face 26 and also to the adjoining underside of the base-section of the ring.
